RECOVERY OF MINERALS IN MARTIAN SOILS VIA SUPERCRITICAL FLUID EXTRACTION

摘要

This investigation involves the determination of the solubilities of inorganic compounds in supercritical carbon dioxide, which is basic property information of these inorganic compounds. If there are inorganic compounds which have associated with them water of hydration which are soluble in supercritical carbon dioxide, then a process which extracts these compounds in supercritical carbon dioxide could be developed to recover water on Mars. In addition, supercritical carbon dioxide may react with certain inorganic compounds producing water as a by-product of the reaction
